This massive commit refactors all of the request methods on the
Fog::Compute[:vsphere] instance to return simple hashes. The behavior
before this commit returned full vmware object references which was a
problem because it was difficult to unit test.
With this patch, it is much easier to add and maintain Mock
implementations of the request methods. This makes adding behavior
tests for the server model much easier.
In addition, test coverage using Shindo has been added. Previously
there was little test coverage of the behavior.
To run the tests:
shindont tests/vsphere/
Without this patch, no actual API calls are being made through the Fog
layer to the underlying rbvmobi later and ultimately to the vSphere
target API.
This patch adds a simple current_time request which is similar to a
"ping" The layers and API are exercised fully using this simple API
call to retrieve the current time on the remote system.
This provides:
>> Fog::Compute[:vsphere].current_time

>> Fog::Compute[:vsphere].requests
[:current_time]
